I ATENT STRAW-STACKER.

SPECIFICATION formingpart of Letters Patent No. 675,250, dated May. 28, 1901.

Application filed February 25, 1901. Serial No- 48,'721. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES L. SHOEMAKER, a citizen of the United States, residing at Mifflinburg, in the county of Union and State of Pennsylvania, have invented certain new and useful Improvements in Straw-Stackers and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to straw-stackers.

The object of the invention is to provide a stacker with an. auxiliary or supplemental trough located at the under side ef the main stacker-trough and designed to carry back to the upper run of the endless conveyer that straw, chafi, and the like which by centrifugal action or otherwise has heretofore been pulled around by the conveyor and allowed to drop under the conveyer and form into a pile,which soon interferes withthe operation of the conveyer and requires to be removed in order to allow the conveyer to operate.

With this and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly'pointed out in the appended claim.

In the accompanying drawings, Figure '1 is a perspective view of the rear end of a separator, illustrating my improved stacker secured thereto. Fig.- 2 is a longitudinal vertical sectional view through the stacker. Fig. 3 is a detail side view of the lower end of the stacker-troughs, parts being broken away to more clearly show the manner of removing the troughs from the thresher.

Referring now more particularly to the drawings, the numeral 1 denotes the main stacker-trough, having at each end pulleys 2 and provided with the usual endless slatted conveyer 3.

4 denotes an auxiliary or supplemental trough, and 5 denotes hanger-arms by means of which this auxiliary trough is secured to the main trough. The lower or inner end of the auxiliary trough is preferably constructed of a curved sheet-metal plate 4 and extends down under the lower pulley 2 and up and partially over the upper run of the conveyor, the said plate being hinged at its lower end to the floor of the supplementary stackertrough, so that it may be swung downwardly to-allow the troughs to be raised to facilitate their removal, the plate 4' being normally held in position by a rod 4 passing beneath the same and through the sides of the sup plemental stacker-trough and having nuts screwed upon its ends to prevent accidental displacement. The side of the trough may have openings 6 to afford inspection of the interior of the trough. The main stackertrough 1 is supported at its lower end by openended castings upon the pulley-shaft journaled in the rear end of the thresher in the usual manner, and that portion of the sup plementary thresher which extends beneath the said shaft is slotted or cut away a sufficient distance, as shown, to allow the stackertroughs to be removed, which is done by raising the said troughs and moving them backwardly a sufficient distance to clear the pulley-shaft, when they can be readily removed, the conveyer-belts being of course previously unbuckled.

In operation, assuming the straw-carrier to be working in its usual way, it will be noticed that the straw and chaif which may cling to the endless conveyor, which has heretofore been allowed to drop upon the ground as the lower run of the conveyor is passing under the trough and which soon forms into a large pile, by the application of the supplemental trough is caused to be carried down by the lower run of the conveyor and up over and upon the lower end of the upper run of the conveyer, where it is carried up and discharged from the upper end of the conveyor in the usual manner.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of my invention will be readily understood without requiring a more extended explanation. Various changesin the form, proportion, and minor details of construction may be made withinthe scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination with a straw-stacker of the endless-apron type, of an auxiliary trough In testimony whereof I have hereunto set placed under the stacker and provided at its my hand in presence of two subscribing Witlower end with a hinged extension which is nesses.
